To what i think on my own view i don't know if i can get more knowledge and understanding to this.
You just have to understand the market, you need to be able to study and know when it’s a right time for you to invest and withdraw your crypto currency. And also remember only invest money you know you can make back even if you lose the money.
I think even understanding the market is not enough, also there is no such tool's that can give you like always a win trade. Trading is like a gambling, sometimes you win and sometimes you lose. What in those two where you will end up? And always only afford what you can lose. Trading requires year's of knowledge in able like to made more wins than losing. Other's always think that crypto is the one gonna make them rich, well for sure others do become rich with trading, but i am so sure not all of them made it to the top.
